Sure we can buy Montanas or Frontiers, great product and consistent in weight, if that is important.
If we need something cheap, I say 30% - 40% (depends who sell them) less cost then Montana, Excel is fine. Their weight ratio is all over, from 188 to 193 grain fro 190grain, but they work. We can use them for practice or Level I or II matches and safe on good bullets for Level III or important shots.
This boils down to how much money we have to buy bullets?
How many of them we want to shoot a year?
